I think the game looks very polished. I tried to play for a bit but I was always getting round 1 and I could upgrade everything. It seems that if you go back to main menu the round numbers do not increase.
Overall I think is an interesting idea. I really liked the tutorial. How did you have time to make all of those nice animations and transitions in just 2 days?

Not sure what you mean about always getting round 1, but glad you liked the parts that did work :D
The chest transition is 4 line renderes expanding in size, which made it quite fast to create.
I did the simple animations for the characters and traps in Unity, and it's almost exclusively just rotating stuff over time.
The movement of the characters was done with through scripts and made use of rigidbodies to handle gravity and velocities :D
